OIL-CAN.

Specification of Letters Patent.

Patented June 4, 1912.

Application filed February 21', 1912. Serial No. 679,056.

To all whom t may concern e Be it known that I, RAYMOND D. SHEP- ARDsoN, a citizen of the United States, residing at Becket, inthe county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

This invention relates to oil cans and has for an object to provide means whereby the bottom of the can is automatically rendered operative or returned to normal position, after liquid is dispensed from the can.

In the drawing forming a portion of this application and in which like letters of reference indicate similar parts in the several views Figure 1 is a vertical section through a can showing the application of the invention thereto. Fig.V 2 is a perspective view of one of the springs. Fig. 3 is a perspective view of the nozzle.

The oil or like dispensing can 1 is provided with an elastic or yieldable bottom 2 whose central portion 3 is disposed below the plane of the adjacent outer wall of the bottom whereby the bottom is free toyield when pressure is brought to bear thereagainst to effect a forced delivery of the liquid from the can. Means are employed herein whereby the bottom will be normally returned to an operative position automatically after pressure is removed therefrom. This means comprises one or more springs 4 which are secured as at 5 to the sides of the receptacle as clearly illustrated in Fig. 1. These springs extend down in the direction of the central manipulating portion 3 of the bottom and their free ends are yieldingly engaged against the bottom as clearly indicated. The nozzle 6 is threadedly connected as at 7 to the short neck 8 of the can and the intake end of said nozzle is provided within the can with a yoke 9 from which depends a threaded stem 10. A spring 11 of .flat leaf form and of arcuate configuration is disposed above the plane of the bottom 2 and its free ends are engaged against the intermediate upper portions of the springs 4 and interposed between the ears 12 upon said springs. In this manner it is evident that the spring 11 is held operal tively associated with the springs 4. A relatively large opening 13 is formed in the spring 11 at the center thereof. This opening is adapted to receive the lower end of the stem 10. A nut or equivalent adjusting element 14 is mounted on the threaded portion 15 of the stem and it may be adjusted thereon so as to engage against the central portion of the spring 11 so that the pressure of the spring 11 against the springs 4 can be quickly changed tov suit the occasion. That is to say when the springs 4, in a measure lose their elasticity the nut 14 can be adjusted upon the stem 10 when the nozzle is removed from the can. The portions 7 and 15 are oppositely threaded so as to permit of the adjustment of the nozzle upon the can without affecting the adjustment of the nut 14.

I claim Y. 1. A can having a yieldable bottom, a discharge nozzle fitted to the can, yieldable means supported by the canr and bearing against the bottom, second yieldable means bearing against the first means, and means on the nozzle engaging against the said second means to regulate the pressure of the second means against the first means.

2. A can having a yieldable bottom, a discharge nozzle removably tted to thel can, springs carried by the can and having portions yieldingly bearing against the bottom, a spring bearing against the iirstsprings, and means on the nozzle bearing against the second spring.

3. A can having a yieldable bottom and a discharge nozzle, a spring carried by the can and yieldingly bearing against the bottom, a second spring bearing against the first spring, and adjustable means on the nozzle adapted to engage against the second spring when the nozzle is in place upon the can.

In testimony whereof I atliX my signature in presence of two witnesses.
